There is not really all that much that I can add to this road test. It is well written and covers most aspects of this 4 speed with overdrive model - exactly the same as my car that I purchased in 1971. I was a little surprised that the engine should have revealed some roughness around the 3500 rpm range, which was not something that I ever experienced.

The main difference between this car and mine, under every day driving conditions relates to fuel consumption. On a memorable all night trip to the North Coast, I averaged sixty miles an hour (in the rain !), with a fuel consumption of 25 miles to the gallon. A totally effortless and safe trip despite the wet road surface, and the car would easily "loaf" along at 80 mph. - and all this with an engine that was well worn !

One modification I have carried out relates to the differential. The diff ratios were as follows:

Mark II A, II B and II C with Auto Box ran a three point nine ratio.
The Mark IIi with Borg Warner thirty five box was fitted with a three point five differential and, quite honestly, it was a somewhat unsatisfactory performer, being quite slow and unresponsive.

The manual four speed with overdrive had a standard four point three differential ratio, but engagement of the overdrive feature on the open road would result in a ratio reduction down to three point five to one. At least two of my cars have been fitted with the Mark III three point five differential which should give a substantial ratio reduction to about two point seven. The cars may well be badly overgeared on account of those differential modifications. One of the reasons why I bought the car that Bryce had bought at the Canberra auction was to provide me with a spare three point nine to one diff ratio. Regards. Styria

I would have thought that 2.7 would be quite a low ratio for the power of the motor. Might not be much fun as you would probably need to disengage overdrive for the smallest of hills. You could probably get away with something like 3.3, but 2.7 seems very low.

I'll be interested in hearing how it goes.

I read that the MKII motors are different manual to auto, with different (lower) compression ratio and I believe different cam. I wonder if this will factor in at all. Power is lower in the auto cars and torque peak is at higher RPM.

Also, with modern tyre sizes the car is going to be under geared compared to when new already.

I suspect that that the tappers are badly in need of adjustment. A "good" Rover engine will be whisper quiet. This one isn't.

Just nit-picking, but the yellow handled screw driver is not a Robver item - had he not described the kit as all original, I would have ignored that shortcoming. Also, a lot of 'stuff' in the boot of the car - a lot of useful or useless spares ? Once knew an owner who made great play of saving old, worn out parts as a means of establishing originality. Getting back to the car again - it is a Mark III, not my favourite version, but nevertheless a beautifully presented car. I wonder about price ? Regards. Styria

.....and here is another 3.5 litre Coupe - I guess, whichever way I look at it, it is quite a beautiful and well proportioned car. Regards Styria

As we know Queen Elizabeth II was a fan of the Rover P5 and had 3-4 of them as her personal self drive cars. She is still often sighted driving land rovers on her estates although for security I don't think she drives herself on the roads anymore. Price Charles first car was a P6 2000TC.

Her first P5B, that replaced a P5.


Her Second P5B that replaced the one above
